Detailed description of identification number:

Also known as serial number or account number, it is a relatively unique code in a certain system, which is equivalent to an "ID card". In a specific thing, the identification number is generally unchanged, and what to use to identify this thing is determined by the rules formulated by the designer himself.

Generally speaking, this rule is designed subjectively according to the specific use environment, such as "employee number", "ID number" and "computer website". There are two main ways of computer operation, logical operation and arithmetic operation. Logical operation is related to the ID function of numbers.

Identification numbers are very common in life. For example, the product model and production number can be pasted on similar things to distinguish them. This can also be called ID.
